Safety function with brake
In the event of a safety-related request from a brake, it must be ensured that the brake is applied in the entire system. For this purpose, the power supply to the brake must be safely interrupted. The safety function to be implemented consists of multiple safety sub-functions.
Example system representation
The safe brake module SBM implements the following safety sub-function:
- Safe disconnection of the power supply to the brake
- The SBM safe brake module safely interrupts the electrical power supply to the brake by disconnecting the safe digital input SBC_P/_M at terminals 1 and 2. The disconnection is performed by a safety relay – e.g. via the SBC (Safe Brake Control) output function.
